Lift-off is set for 22 April
The second Ariane 5 mission of 2011, due for lift-off on 22 April from the European Spaceport at Kourou, French Guiana, will orbit the communications satellite Yahsat Y1A, designed and built by Airbus Defence and Space and Thales Alenia Space.
The 64-minute launch window opens at 21.37 UT (18.37 local time in Kourou, 22.37 British Summer Time).
Yahsat Y1A is the first satellite built for Al Yah Satellite Communications Company (Yahsat), a pioneer in satellite solutions for the Middle East, Africa, South West Asia and Europe.
It is the first part of a fully integrated satellite communications system, comprising the two Y1A and Y1B satellites and ground segment, developed by an industrial team of Airbus Defence and Space and Thales Alenia Space as co-prime contractors for a turnkey system contract led by Airbus Defence and Space.
The Yahsat system will provide a fully secure telecommunications infrastructure for the UAE military, as well as offering innovative solutions to commercial operators for broadcasting, internet trunking via satellite, corporate data networks and other technologically advanced services.
Airbus Defence and Space is also the industrial prime contractor for the Ariane 5 launch vehicle that will place Yahsat Y1A in orbit. Airbus Defence and Space delivers the fully assembled and tested launch vehicle to Arianespace, the commercial launch service provider. The company also supplies all the Ariane 5 stages, equipment bays, flight software and numerous sub-assemblies.
The Airbus Defence and Space teams on site at the Guiana Space Centre are now busy with final preparations for what will be the 57th Ariane 5 launch.
This flight is a double launch, and will also carry the communications satellite Intelsat New Dawn.
